LCMS is a powerful analytical technique used for identification of both unknown and known compounds Mass identification as well as to elucidate the structure and chemical properties of different molecules.

LCMS/MS the determination of both molecular ion and fragment ions permits more accurate identification analysis than identification using molecular ion alone. The fragmentation voltage can be controlled to encourage more stable molecules to fragment increasing the number of compounds which can be identified by LC-MS/MS.

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
